Verizon Samsung galaxy note 4 - 128gb microSDXC card problem

Had the note 3 got the note 4 an gave my wife my note 3. AMAZING phones love then both. But I'm trying maximize storage I've bought many of my favorite movies an TV shows from Google play. An yea the 32gb internal memory is gone. Immediately after getting my note 4. I purchased a 128gb micro SD card. Installed it NOTHING it was a cheap one so I bought Samsungs 128 micro SD card. An still nothing. Went to best buy an spoke with a Samsung rep the card wouldn't even work in his note4 he suggested I buy a SanDisk 128gb card so I did. That being my 4th 128gb micro SD card. I surely figured I'd be golden. Well guess what STILL NOTHING. so I got a 64gb Samsung micro SD card it works great but my 96gb of complete storage is already maxed out. Need more space. Y wound a 128gb SD card work for me?????
